The Duraguard Solution For Durable Construction


With the growing demand for residential and commercial spaces around strategically and well-connected places, the usage/consumption of cement is increasing @ 3-5% per annum. Growing urbanization creates ever-increasing needs for cement. With 460 Million Tonnes Per Annum (MTPA) of cement production capacity as of 2018, India is the second largest cement producer in the world and accounts for over 8 per cent of the global installed capacity, as of 2018. The cement production capacity is estimated to touch 550 MT by 2020. The demand of cement industry is expected to achieve 550-600 million tonnes per annum constantly by 2025 because of the expanding requests of different divisions, i.e., housing, commercial construction and industrial construction.


India has a lot of potential for development in the infrastructure and construction sector, and the cement sector is expected to largely benefit from it. The Government of India is strongly focused on infrastructure development to boost economic growth and is aiming for 100 smart cities. The government also intends to expand the capacity of the railways, and the facilities for handling and storage, to ease the transportation of cement and reduce transportation costs. These measures would lead to increased construction activity, thereby boosting demand for cement. As per Union Budget 2019-20, Government is expected to upgrade 1,25,000 km of road length over the next five years.


In keeping with the present day demands for quicker construction and sleeker structures, cement has emerged as the preferred choice for building materials. For any modern pucca construction in India, cement is needed from the mud mat below the foundation to roof treatment above the roof slabs. Not only does it have a limited carbon footprint, it is also cheaper than steel. Further, as compared to steel, cement boasts of better fire-proof quality and safety. It is mouldable and flexible enough to shape with moulding types, and is a cost-effective construction material. Not many builders use steel, as it requires special tools to use.


Also, concrete buildings offer many safety advantages over steel skeleton structures. As compared to steel, concrete can endure very high temperatures for long periods and offer excellent protection from explosions. Moreover, the construction process with concrete takes lesser time. When time means money, this makes it a particularly attractive option. Unlike steel, it is also possible for large sections to be prefabricated off-site. This again speeds up construction, meaning less time developing and more time using the structure. Companies also offer concrete repairs, which tend to be a lot quicker, simpler and cheaper than other repairs on steel structures.



Additionally, cement has also found its use in grouting, retrofitting, repairs, and in the manufacture of road components, precast components, fibre bound roofing sheets, Hume pipes, and manufacture of wall fill items, among others. The applications with cement are endless, and more recently, concrete door window frames are also a very good sustainable option.


The continuous widespread application of cement-based materials to support human civilization is attributed to their simple modification ability. Among the various cement products available, the Duraguard (DG) range by Nuvoco has emerged as a front runner during various stages of construction. Conceptualized and designed at Nuvoco’s exclusive research and development facility - Construction Development and Innovation Centre (CDIC), the Duraguard range offers varied and innovative solutions to home builders.


Duraguard cement is the mother brand in PPC segment and comes with a unique Void reduction technology that reduces gap between the cement molecules and provides ultimate strength to the building. This helps create a high-density concrete mix that attributes towards structural durability and resistance to cracks. It is perfectly suited for a variety of construction jobs, from building foundations to fixing tiles fixing, from plastering to roof casting. Ordinary cement particles allow seepage of water and chloride, making a structure weak from inside. With the unique Void Reduction Technology, Duraguard increases the strength and density of concrete and stops the attack of harmful elements. Therefore, houses made with Duraguard are strong from inside and last forever.


Another interesting development in the construction segment has been the evolution of fibres. Since Biblical times, fibres have been used to strengthen brittle matrices, but it was only during the 1960s, that steel fibres were proposed as a dispersed reinforcement for concrete. From this development came the next revolutionary product under the DG umbrella – Duraguard Microfibre (DGMF). This is India’s first fibre technology cement that has fibre as ingredient that enhances the bonding process, which in turn helps to resist cracks, reduces permeability, improve impact strength and durability, and provide a smoother surface finish.


Duraguard Microfibre (DGMF) is a product to be believed as fibre is visible to the naked eyes on opening the bag. This next-generation cement in a short span of time, has made its mark in the construction sector for its unique micro-fibre technology. These micro-fibres act as micro-reinforcing agents, and enable the cement to resist seepage, dampness, cracks, shrinkage, and thermal cracks in the years to come. The premium cement has been pre-dosed and pre-homogenized with micro-fibres, resulting in micro-reinforcement of the ‘sand-cement’ matrix to minimize micro cracks, and ensure higher durability. It has been produced from high quality clinker with 48-52% C3S and low C3A content. Along with the high quality, electrostatically precipitated dry fly ash have been sourced from reputed sources, ensuring the product meets the highest quality standards. Its uses have been employed in every stage of construction. From laying of the foundation to plastering and roof-casting, Duraguard MicroFibre Cement ensures structures are protected from micro cracks. In the long run, this has been found to increase service life, and reduce maintenance costs.



In addition to the above two products in this range is Duraguard Xtra – an innovative product with ‘Superset Technology’ for Individual Home Builders (IHB) and retail segments. It uses an optimum amount of water to lend the cement enhanced workability, high compaction and optimum setting time through a unique ball bearing mechanism. It renders balance to the strength and duress of the concrete, making it the perfect companion for building your perfect home. The ultimate benefit to the consumer goes much beyond just instant strength; Duraguard Xtra gives the consumers the assurance of a durable home. Duraguard Xtra leverages the expertise of advanced capabilities in designing products to the needs of its local customers and partners of Nuvoco’s Construction Development and Innovation Centre (CDIC). This product has been developed through continuous consumer engagement, research and thorough understanding of the impact of external elements on the lifespan of buildings. The knowledge we have gained from CDIC - a customer interface zone, where we interact with our stakeholders and capture market expectations, helps Nuvoco offer innovative products to its customers.


In addition, with the rapid growth in construction industry, consumers look for products that will not only set quickly but will provide unmatched strength and safety to the structure. Addressing this need is Duraguard RapidX, a unique OPC (Ordinary Portland Cement), which exhibits quicker setting properties while keeping durability intact. It is produced through a state-of-the-art technology from selected mix of superior grade limestone that makes construction faster irrespective of the design mix. 


Last but not the least is Duraguard Waterseal Cement, the latest entrant to the DG range; Duraguard Waterseal is a Portland Pozzolana Cement with unique water-repelling and damp-lock properties. It protects the construction from water ingress, dampness, and efflorescence, resulting in higher resistance to and better protection from the harmful waterborne environmental pollutants; thereby, increasing the structure’s life and durability. With Quality and Innovation at the core of Nuvoco’s philosophy, Duraguard Waterseal is produced using state-of-the-art technology, where an insoluble coating forms over steel bars and enhances the overall life of the structure. The special mix of Duraguard Waterseal ensures an improved damp-lock process and a faster pace of construction without compromising on strength. It is a path-breaking product in the premium segment and comes in Ad Star bag.


Duraguard Waterseal is best suited for, both, exterior and interior plaster jobs. When used in kitchens, toilets, bathrooms, and cellars, it would keep free from dampness, and hence, result in improved hygiene. Apart from its unique water repellent properties, it also reduces exterior primer paint consumption by 20-25%, if applied directly upon the plastered surface.


The IHB market largely prefers to use ‘A’ category brands of cements for structural concrete that offers consistent good strength. On non-structural concrete or masonry applications, the preference ranges from ‘A’ category to ‘B’ category cements. In the IHB segment, dampness and leakage is one of the most common problem encountered by customers due to low-tech construction methods, materials and poor workmanship. This problem affects the durability and aesthetics of the buildings.



Almost all the cements available in India are plain vanilla, without any specific value-added properties to overcome problems like dampness, leakages. Consumers use chemicals like water resisting agents and other performance enhancers, which is often guided by working masons with a lot of tentativeness and ignorance about dosage and control. Therefore, Duraguard Waterseal adds value in cement and gives consumers functionally better cement that has hydrophobic properties to provide water-resisting/repelling performance.


All the above products under the Duraguard umbrella have made it viable and beneficial to be used at every stage from foundation to the final finished construction. The IHB segment, in fact, has stood to benefit the most from this range. As buyers, they lean towards premium brands of cement for concrete that offers consistently good strength. One of their key concerns, it was observed, was dampness and leakages. With products that address their specific concerns, the Duraguard enjoys an opportunity to inherently add value to cement and give consumers functionally better products for long-lasting homes.
